A brain aneurysm occurs when a section of the brain's artery wall weakens and balloons out. People can live for years without experiencing any symptoms. Most small aneurysms are discovered incidentally during MRI or CT scans.

A ruptured brain aneurysm causes subarachnoid hemorrhage, a life-threatening condition requiring immediate medical attention due to its high mortality and disability rates. Besides monitoring, doctors often recommend lifestyle adjustments to minimize factors that increase pressure on artery walls.

Exercise is essential for overall health, helping maintain a healthy weight, improving blood circulation, increasing stamina, and reducing stress. However, individuals with brain aneurysms should exercise cautiously. Excessive exertion elevates blood pressure and heart rate, forcing blood through the vessels and increasing pressure on already weakened artery walls. This sudden change can cause the aneurysm to grow or rupture. High-intensity activities like marathon running, heavy weightlifting, long-distance cycling, HIIT, crossfit, and contact sports all pose potential risks.

Instead, focus on low- to moderate-intensity exercises such as walking, swimming, light cycling, basic yoga, meditation, stretching, and deep breathing. These activities promote stable blood circulation with minimal impact on blood pressure. Exercise regularly at a consistent pace, avoiding sudden exertion. Maintain steady breathing, avoid holding your breath, and don't overexert yourself. Listen to your body and stop if you experience headaches, dizziness, blurred vision, or nausea.

With a 3 mm aneurysm, regular monitoring is crucial. Your doctor will assess any changes in its size. Aneurysms under 5 mm are not typically treated immediately. However, seek immediate medical attention if you experience severe headaches, vomiting, limb weakness, or altered consciousness. Maintain a healthy diet rich in vegetables and fiber, reduce salt intake, and limit processed foods. Avoid smoking, limit alcohol, get enough sleep, and manage stress.
